The problem
A half-checked prescription is how a dangerous drug combination slips through. Docuity Rx, part of the Docuity suite, makes the safety check part of writing the prescription rather than a separate step someone has to remember.
What it does
Docuity Rx is free, part of the Docuity suite. A prescriber picks the patient, adds each medicine with its dose, and the app checks the whole draft — every medicine against every other medicine, and against the patient's recorded allergies — as they type, using a vocabulary of more than 2,100 real drugs. Anything it can't confidently identify is flagged as not checked, rather than folded into a quiet all-clear.
Issuing a prescription is deliberately hard to do carelessly: it locks only once the prescriber has a real medical-council registration number on file, at least one medicine is listed, and none of them is a controlled substance — those are blocked outright in this version.
Once issued, a prescription can be printed as a proper private-prescription sheet, saved as a PDF, or sent straight to a pharmacy the practice has invited — pharmacies don't appear from an open directory, only by a real invitation. Anyone holding the printed script can scan a QR code to confirm it's genuine without exposing the patient's details.
Key features
A safety check before every prescription
Every medicine on the script is checked against the others and against the patient's allergies before it can be issued, so a dangerous combination is caught while it's still a draft.
Honest about what it couldn't check
A medicine it can't confidently identify is flagged as not checked rather than folded into a quiet all-clear, so a thin result never reads like a clean one.
Controlled substances are simply blocked
This version won't issue a controlled-substance prescription at all — a hard rule, not a warning that's easy to click past.
A real prescriber has to be on file
Issuing requires the prescriber's actual medical-council registration number, so a prescription can't go out from an account that isn't a genuine prescriber.
Print, PDF, or send to a pharmacy directly
A finished prescription becomes a proper printed sheet, a PDF, or a direct send to a pharmacy the practice already works with, whichever the patient needs.
Anyone can verify a script is real
A QR code on the printout opens a public page confirming the prescription is genuine, without showing the patient's name or what was prescribed.
Where it stands
Launched for Jamaica's private-prescription format; controlled substances aren't supported yet. Like the rest of the suite, it makes no HIPAA-certification, SOC 2, or Business-Associate-Agreement claim, and the interaction check is an aid to a prescriber's judgement, not a replacement for it.
Under the hood — for the technically-minded
How it's built
The interaction and allergy check never runs in the browser — every lookup is proxied through the server against the shared drug dataset, and it re-runs on the whole draft each time a medicine is added or removed, so what's on screen always reflects the current list.
Issuing is a gate with several independent locks, and the controlled-substance block is deliberately separate from the interaction data: it runs its own offline check against the raw drug name and fails closed, so it can't be bypassed just because the interaction service is slow or unreachable.
A prescription's lifecycle — draft, issued, sent, received, dispensed — writes to an append-only, chained log the same way EHR's does, and the public verification page is intentionally thin: a handful of facts, nothing that could identify the patient.
The hard problems
A safety check that admits what it doesn't know
The check is coverage-aware on purpose: instead of one pass/fail, it separately reports drug-drug findings, allergy conflicts, and a list of anything it couldn't resolve against its vocabulary — so a prescriber never mistakes 'nothing flagged' for 'everything was checked.'
A hard block that survives an outage
The controlled-substance rule doesn't depend on the interaction service being up. It's a separate, offline check against the drug name at the moment of issuing, and it fails closed — if anything's uncertain, it blocks rather than lets a scheduled substance through.
Pharmacies you actually work with, not a marketplace
There's no open pharmacy directory, on purpose. A pharmacy only enters the system when a specific practice invites it by email, and the two form a verified, ongoing link before anything is ever sent.
